IMPROVEMENT IN MACHINES FOR TREATING RAWHIDE.

Specification forming part of Letters Patent No. ]l't2,346, datedJanuary 18, 1876; application filed November 15, 1875.

To all whom it may concern:

Be it known that I, HERMAN Reyna, of San Francisco city and county,State of California, have invented an Attachment for Rawhide-FullingMachine; and I do hereby declare the following description andaccompanying drawings are sufficient to enable any person skilled in theart or science to which it most nearly appertains to make and use mysaid invention without further invention or experiment.

The object of my invention is to provide an improvement in arawhide-fulling machine for which Letters Patent were granted to me; andit consists in an automatic device by which I am enabled to run themachine in one direction for a suflicient length of time, and thenreverse it, this process continuing automatically until the leather isfinished.

Referring to the accompanying drawing for a more complete explanation ofmy invention, Figure l is a perspective view of my device. Fig. 2 is aside elevation.

In the present case I have shown my. machine as operated by belts; butit will be seen that gears or friction-couplings could be used, ifdesired, and the action of my machine be still automatic.

A is the drum of a machine, which I employ for fulling rawhides orforming it into leather.

This machine is more fully described in Letters Patent granted to me June 22, 1869, No. 91,772, and Letters Patent granted to myself and L.Boyer, March 12, 1868, No. 77,920, and its central shaft has abevel-gear, B, upon its lower end. The pinions G and I) mesh with thisgear at opposite sides, one of them being mounted upon a solid shaft, E,which passes throughthe hollow shaft F of the other, and has thedriving-pulley G keyed to it. The driving-pulley H is keyed to thehollow shaft F, and the loose pulley I runs between them. It will beseen that when the belt from the driving-pulley turns one of thepulleys, the machine will operate in one direction, and when the belt isshifted to the other pulley it will operate in the opposite direction.In order to make this action automatic I employ a belt-shifter, J, whichis a part of, or attached to, a sliding bar, K. This bar is operated bya lever, L, which is hinged or pivoted at M, and works in a slot orlink, N, upon the bar, so that when turned from side to side it willslide the bar in one direction or the other. A weight, 0, is secured tothe top of the lever L, so that as soon as it passes the center it willfall by its own weight and shift the belt suddenly.

In order to operate this lever I have fitted another sliding bar, P, tomove below and parallel with the bar K, and this bar has pins 1" 1" uponeach side of the lever L, so that when the bar is moved it will shiftthe lever. The bar I? has a nut, S, projecting downward from it, and ahorizontal shrft, T, has a screw, U, formed upon it, so as to lit thenut S. A belt from the pulley V upon the shaft E extends to the pulley Wupon the shaft T, and by its action the screw will be turned in onedirection until the lever L has passed the center and fallen over, so asto shift the belt to the other pulley, when the whole mechanism will bemoved in an opposite direction until the screw has again moved the barand reversed the lever. By this construction I am enabled to make mymachine automatic in its action, and it can be left until the work isentirely finished. A frictional coupling or reversing-gearmight be usedin place of a belt, but they would not work as well.

Having thusdescribed my invention, what I claim, and desire to secure byLetters Patent, is

y In combination with the drum A of a rawhide-fulling machine, operatingto twist the leather alternately in one direction and the other, ashifting device for the purpose of making the operation automatic andcontinuous, substantially as described.

HERMAN ROYER.
